[0002] Valves are widely used in industries such as petroleum refining, long-distance pipelines, chemical engineering, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, and iron and steel, and play a crucial role in the national economy. With the increasing global water shortage, the rational utilization and management of water resources have become particularly important. Valves can effectively control water flow, reduce waste, and improve the utilization efficiency of water resources. With the increasing emphasis on water resource management and environmental protection, the market's various demands for valve bodies are constantly growing. Existing valves cannot drain water automatically. For example, China has published a "valve" with the application number: "CN201520549518.0". Its hollow tube inside the buffer device has a buffer member, which has a buffering effect on water flow and changes the water flow direction to a horizontal direction, avoiding the direct vertical impact of water flow on the bottom of the water storage system, thereby preventing sediment from being lifted and muddying the water source. However, it cannot achieve the effect of not flowing water when there is water pressure and flowing water only after the pressure is lost. Therefore, it cannot drain the water in the pipeline when the pipeline is not used for a long time, keep the pipeline free of water or at a low water level, prevent water pollution over time, and it does not have the function of relieving the pipeline pressure to prevent the pipeline from bursting or leaking due to excessive pressure.

[0023] Refer to Figures 1-5 , an adjustable automatic drain valve according to an embodiment of the present invention includes: a housing 1 for fixedly supporting the entire device. A thread 2 is provided on the outer surface of the housing 1 for docking with an internal thread tee or an internal thread elbow. A placing groove 5 is provided inside the housing 1 for placing and fixing the embedded part nut 6. The embedded part nut 6 is fixedly connected inside the placing groove 5 for fixedly connecting the screw rod 7 and realizing pressure regulation through the screw rod 7. The embedded part nut 6 is internally threaded with the screw rod 7 for realizing pressure regulation by pressing down the spring 9. One end of the screw rod 7 is fixedly connected with a control head 8 for controlling the use of the screw rod 7. The other end of the screw rod 7 is fixedly connected with a spring 9 for adjusting the pressure and moving the rubber pad 10. One end of the spring 9 away from the screw rod 7 is fixedly connected with a rubber pad 10 for blocking the water leakage port, thereby realizing closing when the water pressure is high and opening when the water pressure is low. A filter plate 3 is fixedly connected to the inner surface of the housing 1 for preventing the automatic drain valve from being blocked. A limit bolt 4 is provided inside the filter plate 3 for limiting the up and down movement of the rubber pad to prevent deviation and leakage of water and air.

[0024] The limit bolt 4 is movably connected with the rubber pad 10. The rubber pad 10 is connected to the filter plate 3 through the limit bolt 4 for limiting the up and down movement of the rubber pad to prevent deviation and leakage of water and air. A conical groove is provided inside the housing 1. The rubber pad 10 is conical and fits with the conical groove for blocking the water outlet hole with good sealing performance. The rubber pad 10 is movably connected with the conical groove for blocking the water leakage port, thereby realizing closing when the water pressure is high and opening when the water pressure is low. The material of the screw rod 7 is carbon steel for enhancing the material performance. The screw rod 7 is movably connected with the housing 1 for the movement of the screw rod 7. The material of the control head 8 is plastic and the color of the control head 8 is black.

[0025] Working principle: During use, the housing 1 is connected through the internal thread of the threaded tee or the internal thread elbow of the thread 2, and then the screw rod 7 is rotated by the control head 8. The screw rod 7 rotates within the embedded part nut 6 in the placement groove 5, pressing down the spring 9 to adjust the pressure. Then, the solid particles are filtered by the filter plate 3. The pressure of the water flow presses down the rubber pad 10. When the pressure is high, the downward pressure of 11 is large and it is blocked and cannot flow out. When the water flow pressure is small, it flows out, thereby realizing closing under high water pressure and opening under low water pressure. Then, the limit bolt 4 in the filter plate 3 passes through the 11 limit rubber pad and moves up and down to prevent deviation and leakage of water and air.
